• Designed a cross-platform company switcher that propagated decisions across 4 apps — Workforce, QuickBooks Mobile, and GoPayment — partnering with mobile developers from ideation through launch to reach web parity on a unified codebase. Impact: 94–98% sign-in success rate.
• Lead designer on a 10-person cross-functional team for the IES Invitation Hub. Designed the batch invite acceptance flow that lets enterprise accountants accept dozens of client invitations at once. Led the team's decision to migrate from DataGrid to a Table component, unblocking the team 3 weeks before code complete.
• Drove a +2.4 pt lift in invite acceptance rate. Shipped Invite by Firm ID from 0% to 100% production — a new way for QuickBooks clients to invite accounting firms using just a Firm ID instead of email. Publicly praised by a QBO accountant on Meta.
• Championed a performance and loading strategy to scale the company selector for mid-market customers in Intuit Enterprise Suite. Solved for edge cases involving 1,000+ entities without degrading the sign-in experience.
• Spearheaded the unified business profile in QuickBooks. Redesigned the screen where small business owners enter and update their company information so data stays consistent across Payroll, Payments, and tax products — 80.2% of profiles now successfully sync, with ~5K updates per month.
